Sand-BJ (Sand Casting Binder Jetting)

Sand-BJ е BJT вариант за foundry sand molds and cores. Inkjet array депонира furan или phenolic binder върху silica sand powder bed. Готов mold се извлича, готов за molten metal pour: без green machining, без mold making. ISO/ASTM 52900 → BJT.

Sand-BJ елиминира pattern making в casting workflow: старият процес: CNC pattern → mold making → cast. Нов: CAD → print mold → cast. Спестява weeks → days. Особено valuable за: cylinder heads, large valve bodies, art casting, prototype castings (1-10 pcs).
